Maleic anhydride (MAN) copolymers with methyl methacrylate(MMA), ethyl methacrylate(EMA), methyl acrylate(MA), ethyl acrylate (EA) and buthyl acrylate (BA) ( in a 1:1 mole ratio) were synthesized by free radical polymerizations method under vacuum -azobis(isobutironitrile)(AIBN) as an initiator of reaction at 701C. The copolymer compositions were determined using related 1H NMR spectra techni...
The title compound, C(17)H(15)NO(5), adopts an E conformation with respect to the C=C double bond of the phenyl-acrylate unit. The phenyl ring and methyl acrylate group of the phenyl-acrylate unit are disordered over two sets of sites with site-occupancy ratios of 0.705 (5):0.295 (5) and 0.683 (3):0.317 (3), respectively. The mean plane through the benzene ring of the phenyl acrylate makes dihe...
Poly(vinyl acetate)-b-polystyrene, poly(vinyl acetate)-b-poly(methyl acrylate) and poly(vinyl acetate)-b-poly(methyl methacrylate) block copolymers with low polydispersity (M(w)/M(n) < 1.25) were prepared by successive reversible addition-fragmentation chain transfer (RAFT) polymerization and atom transfer radical polymerization (ATRP) employing a bromoxanthate iniferter (initiator-transfer age...
In the title compound, C(12)H(11)NO(2), the indole and methyl acrylate mean planes are inclined at an angle of 10.6 (1)°. In the crystal, N-H⋯π inter-actions link mol-ecules into chains along [010] and weak inter-molecular C-H⋯O hydrogen bonds further consolidate the crystal packing.
5- hydroxyisoquinoline undergoes a smooth reaction with alkyl propiolates in the presence of triphenylphosphine (15 mol%) to produce the corresponding (E)-alkyl 3-(isoquinolin-5-yloxy) acrylate in good yields. When the reaction was performed by 2-methyl 4-hydroxyquinoline and 3-nitro 4-hydroxypyridine, similar aryl vinyl ethers were obtained.
In the title compound, C11H10O4, the methyl acrylate sub-stituent adopts an extended E conformation with all torsion angles close to 180°. The conformation of the keto group with respect to the olefinic double bond is typically S-trans. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(8) graph-set motif. The dimers are further lin...
In the mol-ecule of the title compound, C(17)H(15)BrO(3), the rings make a dihedral angle of 75.54 (17)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers, and the π-stacked dimers inter-act with neighbouring dimers via C-H⋯π stacking inter-actions.
